Help me solve a keyswitch problem
« on: Thu, 17 July 2025, 09:18:12 »
My first mechanical keyboard was a Ducky One2 TKL Skyline with Cherry MX Blue switches. Eventually I decided to upgrade to a more customisable keyboard, so I got a Keychron Q1 Pro, in which I put Kailh Box Jade switches. However, I found that my typing accuracy was much worse on the new keyboard. Which didn't make sense to me since Jades are very similar switches to Cherry Blues, with the same actuation force (50g), and also the keycaps are PBT in both cases. After more experimentation, I finally resorted to putting Cherry Blue switches in the Keychron, and I do think my typing has improved again. The only explanation I can see is that Cherry Blues have a pre-travel of 2.2mm, whereas Box Jades have a pre-travel of 1.8mm, which meant they registered presses too soon for my typing style. So I have four questions:

1. Do you think it's plausible that the tiny 0.4mm difference in pre-travel could really make a difference to my typing accuracy, or is it just a placebo?

2. If it's not that, what else could be responsible for the difference? Is there potentially some other mechanical disparity between the Ducky and Keychron boards that I'm unaware of?

3. I don't like the sound of the Cherry Blues compared to the Box Jades – among other things, it's inconsistent (some of the individual switches seem to have a more piercing high-frequency click). Is there a good alternative for clicky switches with a pre-travel of 2.2mm or more? (I did try Kailh Box Navy in the hope the higher actuation weight would solve my typing issues, but they were just too heavy.)

4. If not, how do I improve the sound of the Cherry Blues I'm stuck with?

this is just conjecture, but you could try to increase the width of the debouncing filter. this is not well known by non technical people, but when you actuate a switch it is not a binary off/on. instead the voltage takes a little to rise to `high` and due to the mechanics of a switch it will bounce between `high` and `low` quite a few times. how long the signal takes to stabilise is of course dependent on the switch, so there is a (small) chance that the jades bounce longer.
the keychron q series boards run qmk firmware, which let's you change the debounce filter. i have made good experiences with a 8 milliseconds debouncing filter. might be worth a try. if you need help, pm me.
